NAME

     ofisa -- introduction to machine-independent Open Firmware ISA bus support and drivers

SYNOPSIS

     ofisa* at mainbus0
     XX*    at ofisa?

DESCRIPTION

     NetBSD includes a machine-independent ISA bus subsystem and several machine-independent ISA device drivers.  The ofisa bus uses Open Firmware
     to determine how to attach devices.

HARDWARE

     NetBSD includes machine-independent Open Firmware ISA drivers, sorted by device type and driver name:

   Disk and tape controllers
	   wdc	 Standard Western Digital type hard drive controllers: MFM, RLL, ESDI, and IDE/ATAPI.

   Serial and parallel interfaces
	   com	 NS8250-, NS16450-, and NS16550-based serial ports.

	   lpt	 Standard ISA parallel port interface.

   Network interfaces
	   cs	 Cirrus Logic Crystal CS8900 Ethernet interfaces.

   Sound cards and MIDI interfaces
	   ess	 ESS Technology AudioDrive 1788-, 1888-, 1887-, and 888-based sound cards.

   Miscellaneous devices
	   joy	 Game (joystick) adapters.
